Curt Schilling, the Hall of Fame pitcher.

His stuff was never as good as the young Dwight Gooden’s. It was never as good as Nolan Ryan’s or Roger Clemens. Or either of his teammates: Randy Johnson and Pedro Martinez. Granted, it was really good, and Greg Maddux should be even more respected in this regard.
But what Schilling did incredibly well was not allow runners to reach base, unless they earned it themselves. Something even more valued in this day and age with the growing understanding of On Base Percentage.
